摘要： Controlling the transmission of reference signals in a wireless communication network includes transmitting reference signals at recurring occasions for use in making reference signal measurements at receiving radio equipment. The reference signals are muted in certain ones of the occasions according to a muting configuration. Muting configuration information indicating the muting configuration is transmitted to inform the receiving radio equipment of the muting configuration. The muting configuration information comprises a bandwidth parameter identifying the portion of reference signal bandwidth to which muting applies; and/or a subframes parameter indicating the number of consecutive subframes within an occasion to which muting applies; and/or a muting occasion parameter indicating occasions to which muting applies.

摘要： A method of operating a wireless device that is configured to perform a timing measurement procedure that involves transmission of a reference signal during a timing measurement period is disclosed. The method includes determining that the wireless device is configured for antenna port switching of an antenna port configuration for transmitting the reference signal during the timing measurement period, and in response to determining that the wireless device is configured for antenna port switching of the antenna port configuration for transmitting the reference signal during the timing measurement period, adapting at least one of the timing measurement procedure during the timing measurement period and a configuration for antenna port switching of the antenna port configuration for transmitting the reference signal during the timing measurement period.

摘要： According to some embodiments, a method for use in a user equipment (UE) operable to transmit a sounding reference signal (SRS) on a plurality of carriers comprises: obtaining an indication to perform SRS carrier-based switching for a carrier; adapting a parameter for uplink transmit power control in response to the obtained indication; and transmitting an uplink signal using the adapted parameter while meeting at least one predetermined uplink power control requirement. According to some embodiments, a method for use in a network node operable to receive a SRS on a plurality of carriers comprises: sending, to a UE, an indication to perform SRS carrier-based switching for a carrier; and receiving, from the UE, an uplink signal based on the parameter for uplink transmit power control adapted in response to the sent indication, wherein the uplink signal meets at least one uplink power control requirement.

摘要： Embodiments include methods performed by a user equipment (UE) of associating positioning signals with beams transmitted in a wireless network that includes a location server and a base station. Such methods include receiving assistance data from the location server. The assistance data includes a configuration of positioning signals to be transmitted by the wireless network and information identifying at least one relationship between the following: one or more positioning beams that carry the positioning signals, and one or more radio resource management (RRM) beams that carry RRM signals. Such methods include receiving, from the base station, the positioning signals via the one or more positioning beams based on the at least one relationship between the positioning beam(s) and the RRM beam(s). Other embodiments include complementary methods for base stations and location servers, as well as UEs, base stations, and location servers configured to perform such methods.

摘要： Embodiments include methods performed by a second network node in a wireless communications network that includes a first network node, the second network node, and a third network node. Such methods include receiving, from the first network node, a configuration comprising a pattern indicative of whether or not each of a plurality of Synchronization Signal Block (SSB) transmissions, that are configured based on a nominal timing, are actually transmitted by the third network node according to the nominal timing. Such methods include, based on the received configuration, managing transmission and/or reception configurations for one or more of the following: one or more cells served by the second network node; and one or more UEs served by the second network node via the one or more cells. Other embodiments include second network nodes configured to perform such methods.
